 * Backward incompatible changes
   * `Sentry.capture_exception/1` now returns a `Task` instead of `{:ok, PID}`
-  * Sentry.Plug `:scrubber` option now defaults to newly added `Sentry.Plug.default_scrubber/1`
   * Sentry.Plug `:scrubber` option has been removed in favor of the more descriptive `:body_scrubber`option, which defaults to newly added `Sentry.Plug.default_scrubber/1`
   * New option for Sentry.Plug `:header_scrubber` defaults to newly added `Sentry.Plug.default_header_scrubber/1`
   * Request bodies were not previously sent by default.  Because of above change, request bodies are now sent by default after being scrubbed by default scrubber.  To prevent sending any data, `:body_scrubber` should be set to `nil`
